Abstract: Apparatus suitable for processing semiconductor slices, comprises a tank (1) for receiving a jig carrying semiconductor slices, a first supply line (2) for supplying a processing liquid to the tank (1), a supply valve (3) for controlling liquid supply through the first supply line (2), the supply valve (3) being operable in response to changes in fluid pressure at a control port (4) of the supply valve (3) and a second supply line (5) for supplying fluid to the control port (4) to control operation of the supply valve (3). The second supply line (5) communicates with an inlet (8) of the tank (1) via a control valve (7) which is operable in response to changes within the tank to control the fluid pressure at the control port (4) and so control operation of the supply valve (3).In the arrangement shown in FIG. 1, a valve member (7a) of the valve (7) is carried by a platform (9) pivotally mounted within the tank (1).
